[ALPS-users] Results is different for worm(sse) and wolfram mathematica

First , I was obtained density of magnetization and density of energy curves of isotropic Heisenberg model on square lattice (2x2) using worm and dirloop_sse. After I was obtained these curves with wolfram mathematica. Curves for magnetization density(density of energy) obtained with mathematica and worm(sse) is strongly differ one from another.They must match. I was attached the files of mathematica and Heis2x2.py.
